Best Chrome extension for YouTube in 2026

Updated May 4, 20265 min read

YouTube already does a lot. A great extension fills the remaining gaps — speed beyond 2×, bookmarks, synced lyrics, and fine-grained audio control. Here is what to look for in 2026.

  1. 1
    Step 1

    Go beyond YouTube's 2× speed cap

    YouTube's built-in speed tops out at 2×. Glitch extends that range — free users get 0.5×–2×, Pro users get 0.25×–16×.

    Step 2

    Loop a precise timestamp range

    Full-video loop is built into YouTube, but looping a specific segment (AB loop) is not. Glitch adds AB loop so you can repeat a chorus, a technique, or a tricky explanation endlessly (Pro).

    Add bookmarks with labels

    YouTube's timeline shows chapters, but not personal bookmarks. Glitch lets you drop timestamped bookmarks with labels and revisit them from the panel any time.

    Get word-by-word synced karaoke lyrics

    Glitch fetches word-by-word synced lyrics for music videos and displays them in four animated styles — Sweep, Glow, Bounce, and Beat (Pro). No separate app needed.

    Boost audio for quiet uploads

    Some YouTube videos are recorded quietly. Glitch's volume boost pushes audio beyond the browser's own cap so you can actually hear them (Pro).

    Download captions as an SRT file

    For any video with a transcript, Glitch can export the captions to an SRT file so you can use them offline or drop them into a video editor.

FAQ

  • Does Glitch interfere with YouTube's built-in features like chapters or likes?

    No. Glitch adds its own toolbar and panel without replacing or hiding anything YouTube already shows.

  • Can I use it on YouTube Music as well?

    Yes. Glitch works on any YouTube page with a video player, including YouTube Music.

  • Is the karaoke feature limited to popular songs?

    Lyrics come from a public database. Coverage is broad for mainstream music but may be missing for niche or independent artists.
